"But it isn't the case," was Todd's reply. "The physical characteristics to which I refer only mean that a man is likely to develop along the wrong lines. They are like the stars which, as Shakespeare remarked, 'incline, but do not compel.' If you remember, he added, 'The fault, dear Brutus, lies in ourselves.' Therefore, if a detective of the modern school is working on a case and he comes across a man who bears one or more of these very certain brands of Cain, he watches that man very carefully--at least until he is convinced that he is innocent. You can't arrest a man simply because he looks like a crook, but it is amazing how often the guideposts point in the right direction." "Anyone present that you suspect of forgery or beating his wife?" came in a bantering voice from the other end of the table. "If you're in earnest," answered the government agent, "lay your hands on the table." And everyone present, including Rockwell, cashier of the Central Trust Company, placed his hands, palm upward, on the cloth--though there was a distinct hesitation in several quarters. Slowly, deliberately, Todd looked around the circle of hands before him. Then, with quite as much precision, he scanned the faces and particularly the ears of his associates. Only once did his gaze hesitate longer than usual, and then not for a sufficient length of time to make it apparent. "No," he finally said. "I'd give every one of you a clean bill of health. Apparently you're all right. But," and he laughed, "remember, I said 'apparently.' So don't blame me if there's a murder committed before morning and one or more of you is arrested for it!" That was all there was to the matter until Todd, accompanied by two of his older friends, left the grill and started to walk home. "That was an interesting theory of yours," commented one of the men, "but wasn't it only a theory? Is there any real foundation of fact?" "You mean my statement that you can tell by the shape of a man's head and hands whether he has a predisposition to crime?" "Yes." "It's far from a theory, inasmuch as it has the support of hundreds of cases which are on record. Besides, I had a purpose in springing it when I did. In fact, it partook of the nature of an experiment." "You mean you suspected some one present--" "Not suspected, but merely wondered if he would submit to the test. I knew that one of the men at the table would call for it. Some one in a crowd always does--and I had already noted a startling peculiarity about the forehead, nose, and ears of a certain dinner companion. I merely wanted to find out if he had the nerve to withstand my inspection of his hands. I must say that he did, without flinching." "But who was the man?"
